How long does roundup stay in a container?

Roundup, a glyphosate-based herbicide, can last indefinitely in a sealed container if stored properly. However, once opened, its effectiveness can diminish over time, typically within 2-3 years, especially if exposed to extreme temperatures or direct sunlight. It's essential to follow the manufacturer's guidelines for storage and check the expiration date on the label for optimal use. Always ensure that the container is tightly sealed when not in use to prolong its shelf life.
